The scientific basis and the future possibility for ischemic resistance training
Skeletal muscles can adapt themselves to exercise stimuli with varied changes in their mechanical and metabolic properties. These changes have been shown to be specific to the type of exercise stimuli: intense resistance exercises generally cause increases in muscular size and strength), whereas exercise with much smaller loads (endurance exercise) results in an increase in muscle oxidative capacity without considerable increase in muscular size. However, Takarada et al. have previously shown that low-intensity resistance exercise combined with vascular occlusion induces a marked hypertrophy and concomitant increase in strength, even if the exercise load is much lower than that expected to induce muscular hypertrophy.

In KAATSU training, (1) creating a program to improve the muscle functions of top athletes, (2) applying it to the rehabilitation of patients with cardiovascular diseases such as heart failure, and (3) applying it to motor learning and rehabilitation making use of plastic changes due to MI stimulation in ischemia that triggers muscle contractions, and (4) creating a protocol to alleviate the feeling of fatigue during exercise based on the relationship between the feeling of having made an effort, and cortex related fields that integrate perception and information on exercise.
The benefits and mechanisms behind “KAATSU training” were first reported by Takarada et al. in 2000. The author himself obtained a patent on the training equipment and achieved many successful results in not only sports but also rehabilitation. Moreover, he is continuing his research to this day into its effect on brain functions from a neuroscientific perspective (human cognitive and behavioral science). It is obvious from looking at the number of quotations from his papers that he is a leader in this field of research.
